Problems solved by technology

[0006] Although the above-mentioned academic achievements have carried out some research on the recovery and floating of eutrophic algae in lakes, their test methods and means only collect the floating algae in the lake bottom mud, while ignoring the sinking algae. algae, so none of the above studies can conduct accurate qualitative research on the seasonal differences of lake bloom outbreaks and the dynamic characteristics of vertical migration of most bloom algae
[0007] Through the patent search, no experimental method and corresponding collection device patents have been found regarding the simultaneous capture of floating algae and sinking algae as samples by a collection device

Embodiment approach 1

[0041] Embodiment 1: A test and analysis method for eutrophic algae in lakes

[0042] The present invention provides a test analysis method for eutrophic algae in a lake, by setting a collection device with two mutually independent collection systems for floating and sinking algae at a depth of a certain water body of the lake to simultaneously capture the floating algae and the algae. The sinking algae was used as the algae sample for the test analysis, and according to the comparative analysis of the collected floating algae samples and the sinking algae samples, the vertical migration of algae at a certain depth in the lake and the changes in the algae bloom during the occurrence and development of the lake were obtained. play a role.

[0043] Test demonstration of analytical method of the present invention:

Embodiment approach 2

[0056] Embodiment 2: A sample collection device for capturing floating-sinking algae

[0057] The present invention also provides a sample collection device specially used to capture floating-sinking algae, so as to realize the sample collection in the above-mentioned test and analysis method for eutrophic algae in lakes. The sample collection device can not only capture floating algae at the same time and sinking algae, and the structure is very simple, very easy to operate, and the reliability of the sample is high.

[0058] See attached Figure 1-Figure 4 .

[0059] The overall structure of the acquisition device is as follows:

[0060] It has a floating algae capture system that can independently capture floating algae in the lake and a sinking algae capture system that can independently capture sinking algae. These two systems are fixed side by side parallel to each other and inverted; The sample collection inlet of the floating algae trapping system is arranged vertic...

Abstract

The invention relates to a test analysis method for lake eutrophicated algae and the sample acquisition device. The test analysis method of the invention can accurately, qualitatively, and quantitatively analyze the function of various algae in upward-floating and sinking process by simultaneously collecting upward-floating algae and sinking algae in a lake at a depth as samples. The sample acquisition device with simple structure is special for respectively collecting the algae samples in upward-floating and sinking process by using two built-in algae collecting systems opposite in direction, both the manufacturing and the on-site mounting of the device, and the acquisition of the samples are simple and easy, in addition, the installation depth can be adjusted according to the actual water depth and research demands.

Description

technical field [0001] The invention relates to a test analysis method for eutrophic algae in lakes and a sample collection device specially used for simultaneously capturing floating and sinking algae. Background technique [0002] Every year at the end of spring and early summer, with the increase of temperature, the increase of light and the change of wind direction and speed, the physical and chemical properties of the water-sediment interface and the environmental conditions of the lake have also undergone significant changes. A large number of algae cells The dominant algae cells that floated up to the surface of the lake took advantage of their own competitive advantages to reproduce in large numbers and rapidly, and the water bloom broke out. [0003] For this reason, people have carried out some research on the recovery and floating of eutrophic algae in lakes: [0004] Research 1: By setting algae cell traps on the surface of the sediment, the change of pigment co...
